164 ICOSAND. POLYGYN. 



brous above hairy beneath^ petals ovate longer than the cal., 

 stern ascending, E. B. t. 2389. 



Hab. Werron hill and the East rocks of Clova, G. Don. FL May^ 

 June. 11 . 



This is the second » instance I have to record of a plant which had 

 heretofore been considered a native of N. America only, having 

 been found upon the eastern side of Scotland by the late Mr. G, 

 Don. It is totally \mlike any other British species ; does not ex- 

 ceed 4 — 5 inches in height, and is terminated by 3 or 4 rather 

 large white flowers. 



8. P. Fragaria {barren Straivherry), leaves ternate, leaflets obo- 

 vate deeply serrated silky on both sides (especially beneath), 

 petals obcordote as long as the cal., stems procumbent. Poi- 

 ret, Encycl. Lightf.p. 268, and E.B. t. 17S5 {Fragaria 

 sterilis). 



Hab. \^''oods, banks, and dry pastures. Fl. March, April. 1/ . 



Peduncles terminal, single or two together. Flowers white. This 

 w-ants the essential character of Fragaria, and is rightly placed by 

 the continental authors in the present genus. Seeds, or rather 

 seed-vessels, rugose, not smooth as in Fragaria, according to 

 Smith's definition of that genus. 



9. TORMENTILLA. 



1. T. officinalis {covinion Tormentil), leaves ternate all sessile, 

 leaflets lanceolate inciso-serrate, stem nearly erect dichoto- 

 nions. Light/, p. 272 (T. erecla). E. B. t. S63. 



Hab. Barren and heathy places, common. F/. June, July. % . 

 Root large and woody, used medicinally, and by the Laplanders for 



staining leather of a red colour. Stem weak, 6 — 8 inches long. 



Peduncles axillary and terminal. Flowers rather small, yellow, 



drooping before expansion. 



2. T. reptans {trailing Tormentil), leaves ternate on footstalks, 

 leaflets obovato-cuneiform inciso-dentate, stem prostrate. 

 Lightf. p. 273. E. B. t. S64. 



Hab. Borders of fields and waste places, but not common, Sibbald. 

 I^I. side of the canal, Possil marsh, below the bridge, Hopk. Road- 

 side between Hamilton and Cambuslang, Mr. Murray. -Near Kirk- 

 caldy, Mr. Stewart. Near Ardvorlich, Mr. Arnott. Road-side be- 

 tween Glasgow and the village of Bowling j and near Moulinarn, 

 Perthshire, Maugh. Fl. June, July. 21 . 



Stems prostrate, but not rooting, varying much in length. Flovwrs 

 twice the size of the last. This, as well as the last species, has some- 

 times 5 petals and 10 calycine segments ; and then the plant be- 

 comes a perfect Potentilla, with which it accords entirely in habit. 

 Many of the continental botanists, on these accounts, abolish the 

 genus Tormentilla : and Scopoli has done so with the remark " Mo- 

 noculum hominem ab humano genere quis separabit ?" 



" The first was Junciis tenuis.
